Application filed April 19, 1967.

To all whom it may concern:

Be it known that 1, JOHN BRIERLY HEIGH- INGTON, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Machines for 'iooling Stone, Natural or Artificial, and other lviaterial, of which the followin is the specification.

My invention relates to improvements in machines for tooling stone, natural or artificial, and other material, and the object of the invention is to devise a machine of this class, whereby stone or other material having a surface of any shape, form or contour may be tooled quickly and in a crisp manner.

A further object is to economize both time and labor in the tooling of the stone.

A still further object is to tool the stone, if desired, without disturbing it.

To effect these objects my invention consists of a special feed table to receive and adjust the stone, a vertical standard a cross frame adjustably supported thereon and a jointed arm carried by the cross frame, a cutting tool located at the outer end of the arm and means for Listing arm and driving the same all as hereinafter described.

Figure 1 is a perspective view of my improved machine for tooling stone. Fig. 2, is a perspective view of the standard with the mechanism supported thereby. Fig. 3, is a view partially in section showing the arm and connection to the cross frame carried by the vertical standard. Fig. 1, is a plan view of Fig. 3, the cross frame being broken away and in section. Fig. 5, is a sectional detail of the cutting tool. Fig. 6 is a face view of the means for adjusting the cutter. Fig. 7 is a View of the crossframe looking from the back, a portion of the frame being broken away to show the worm spindle and connected parts. Fig. 8 is a cross'section on the line ab Fig. 7. Fig. 9 is a cross-section through the feed table, and Fig. 10 is an elevation of the standard, the bearings therefor being in section.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the frame of the table provided with a grooved guide-way A.

B is the adjustable table formed with sides B having tongues B, which run in the guide-ways A, a planular,. horizontal top B Specification of Letters Patent.

and a bottom B having a toothed rack B extending underneath it from end to end.

C is an arbor provided with a hand wheel C. The arbor C is journaled in suitable hearings in the frame A and provided with a pinion U", which meshes with the rack B 1 It will thus be seen that by means of the hand wheel the table may be adjusted into any position desired. it is held in any position to which it may be adjusted by the ratchetshaped toothed rack D engaged by the pawl D pivoted on the bracket D attached to the frame A.

E is a standard rotatabiy mounted on a suitable base E its upper end being ournaled in a plate E attached to some fixed structure. Standard E has a rectangular portion E having a depressed toothed rack E on one side thereof.

F is a divided sleeve rectangular in cross section fitting on the rectangular portion E of the standard E. F is a cross frame attached to or forming part of the sleeve F.

G are brackets secured one on each side of the standard E and having studs G at their outer end upon which are ournaled the pulley wheels G The brackets G are lo cated above the rectangular portion E of the standard.

H are ropes connected to the cross frame F and extending over the pulleys I are the counter-balancing weights located at the lower free ends of the ropes H.

J is a ring attached to or forming part of the standard F) near the bottom and provided with holes J into which a lever is inserted when it is desired to turn the standard to swing the frame F to carry the tool into any desired position.

The base E is provided with an upwardly extending lug E through which extends a screw spindle E having at the outer end a handle ll. By swinging the handle the screw spindle may be turned, so as to jam against the standard and thereby prevent it moving. It K is a pinion secured on the crank shaft K, which is journaled in bearing brackets K forming part of the divided sleeve F. The pinion K meshes with the rack E By turning the crank handle of the shaft K the divided sleeve and consequently the frame F may be raised or lowered to any desired height.

The cross frame F is provided with a tubular portion F strengthening ribs F behind such tubular portionand forming a Web between it and the divided sleeve, one portion of which the webs form a part of.

The front portion of the cross frame F is made in the form of a grooved guide-way F which carries the plate F the wear of which is taken up by a strip F located above the plate and held down by suitable set screws F. The plate F is provided with a cylindrical boss F at the front havingv an annular groove F.

L is a cross head having a cylindrical portion L, which fits exteriorly over the cylindrical portion F and has set screws L extending therethrough into the annular groove F in order to securely hold the cross head in position and yet permit it to turn freely.

L is a worm wheel or rim formed on the exterior of the cylindrical portion L.

M is a worm carried by a spindle M journaled in suitable bearings M forming part of the plate F;

L is a hand wheel secured on the spindle M and designed to be manipulated so as to turn by means of the worm M and worm rim L the cross head on its pivot pin 2, which extends through the center of the cross head and a center boss 3 forming part of the plate F The cross head L is provided with arms L and pins 3 on the ends of which is journaled the arm frame 4. The arm frame 4 has an inwardly extending portion 4 on which is carried an electric motor 5. As the portion 4 and motor 5 are located at the innerend'of the arm frame 4 it will be readily understood that they form a counter-bah ance'for the'mechanism carried on the outer end of the frame and hereinafter described.

In order to adjust the plate carrying the cross head L and arms extending outwardly from same, I provide the following mec anism.

N N is a Worm spindle extending from end to end through the tubular portion F and journaled in bearings in the ends of such tubular portion.

N is a gear pinion secured at one end and N is a gear wheel meshing therewith and provided with a manipulating handle N The worm spindle N passes through a pair of brackets 5 attached to or forming part of the plate F and also through a threaded gear pinion located between the brackets 5.

7 is a gear pinion meshing with the gear pinion 6 and located on the spindle 8, which is journaled in suitable bearings within the tubular portion F of the cross frame F.

9 is a ratchet wheel secured on the spindle 8 and projecting through a slot 10 in the plate F 11 is a bracket secured to the plate F and provided with a slotted end 11.

' 12 is a lever fulcrumed on the rod 8 and carrying by means of a pin 12. the pawl 12 .which engages with the ratchet'wheel' 9.

definite step-by step movement.

It will nowbe seen that by manipulating the lever 12 the plate F and mechanism and tool carried thereby maybe moved laterally to any position desired accurately and with a fine adjustment, the gear wheel 7 meshing with the gear wheel 6 on the worm spindle N in order to effect this movement. To restore the plate F quickly to its initial position or primary position I utilize the hand wheel N which turns the worm spindle N' quickly in the brackets 5 and thereby adjusts the plate rapidly. Of course, it will be understood that the plate F as well as the arm and tool connected thereto may be adjusted quickly by means of the hand gear wheel N laterally in both directions, but for line adjustment I prefer to use the lever 12.

The frame 4 hereinbefore referred to carries at the outer end aspindle O, which carries the pulley O. The pulley O is connected by a belt 0 to a pulley O on the shaft of the motor 5.

13 is an arm frame journaled on the spindle O on each side of the pulley O and carrying at the lower end the spindle O 0 is a pulley secured on the shaft 0 and connected by a belt 0 to a pulley O on the s indle O 14 are handles secured to the frame 13 on each side thereof and designed for the pur pose of swinging said frame as desired.

The spindle O is provided with an enlargement forming a shoulder 0 against wiich fits a loose sleeve 0".

P is a disk provided with a central slot P through which extends the sleeve 0.

P is a plate having a central opening loosely fitting the sleeve 0 and vertical slots P through which extends set screws P securingthe plate P to the disk P and thereby mounting the disk P on the sleeve so as to be capable of adjustment. The disk P is also-provided with a hole P and weighting boss P P is adisk provided with an outer rim within which fits the disk P secured therein by the annular gaging ring P fastened to the face of the rim.

Q are a series of disks of carborundum or other suitable cutting material, which are separated by washers Q, the innermost of which abuts the bushing 0 The disks which form the cutting tool for the stone are held in place by a nut Q on the outer reduced threaded end of the spindle 0 It will also be seen that by adjusting the set screws 1, that the depth of the cut may be regulated as well as the wear of the cutting disk forming the cutting tool. compensated for.

By such a construction as I describe I am enabled not only to feed the stone into any position underneath the tool Q, but also I am enabled to move the tool located on the free end of the double-jointed arm 4, l3, laterally on the tubular frame F to any point desired. is the tool is balanced it is readily manipulated. The position of the tool and th frame, which carries it, may be also raised or lowered with facility and the frame and tool may be swung to any desired. position laterally, so that the tool may be worked at any desired angle horizontally. It may be also worked obliquely for it will be readily seen that the arm 4 carrying the tool is cap able of being swung on its pivot pin 2 by means of the worm hf operated through the hand wheel If. I have, therefore, provided in my invention a most complete means whereby a tool may be manipulated to perform all functions necessary to tool stone into all practical shapes or contours.
